The telomerization of 1,2- and 1,3-dienes with benzenesulfinate dihydrate catalyzed by palladium(0) has been promoted by the presence of carbon dioxide.
thermodynamically-stable isomers is negligible. On the other hand, the palladium-catalyzed sulfonylation of allylic acetates with sodium benzenesulfinate is accompanied by the isomerization to give the thermodynamically-controlled products selectively. These results can be explained by assuming that allylic nitro compounds are more reactive to the palladium catalyst than allylic acetates and sulfones.

Highly dispersed palladium on graphite (Pd/Gr), carbon (Pd/C) and alumina (Pd/Al2O3) have been employed as catalysts in substitutionreactions of allylic esters with nucleophiles such as benzenesulfinate and diethyl malonate anions, and 1-(1-cyclohexen-1-yl)pyrrolidine.
高度分散的钯/石墨(Pd / Gr),碳(Pd / C)和氧化铝(Pd / Al 2 O 3)已用作烯丙基酯与亲核试剂(如苯亚磺酸盐和丙二酸二乙酯)的取代反应中的催化剂, -(1-环己烯-1-基)吡咯烷。

Allylicnitrocompounds undergo denitro-sulfonylation catalyzed by Pd(PPh3)4 or Pd(PPh3)4 +NaNO2 with PhSO2Na·2H2O to afford allylic sulfones regioselectively.
